A company has a VPC with a public subnet and a private subnet. An Amazon EC2 instance in the private subnet needs to download security patches from the internet, but the instance must not be directly accessible from the internet. The SysOps administrator configured a NAT gateway in the public subnet and added a route in the private subnet's route table pointing 0.0.0.0/0 to the NAT gateway. The instance's security group allows all outbound traffic. However, the instance still cannot reach the internet. What is the most likely missing configuration?

A company has an Amazon VPC with a CIDR block of 10.0.0.0/16 and an AWS Site-to-Site VPN connection to an on-premises data center. The on-premises DNS servers host a private domain 'corp.example.com'. The SysOps administrator needs to enable EC2 instances in the VPC to resolve DNS names for 'corp.example.com' using the on-premises DNS servers. Which Route 53 feature should be configured?

A company operates a web application behind an Application Load Balancer (ALB). The SysOps administrator needs to block incoming requests from specific geographic locations (countries X and Y) and also enforce a rate limit of 100 requests per IP address per 5-minute window to mitigate DDoS attacks. The solution must be centrally configured and apply to all requests handled by the ALB. Which AWS service should be used to implement these requirements?

A company has multiple VPCs in the same AWS account and Region, each with overlapping CIDR blocks (10.0.0.0/16). The SysOps administrator needs to establish connectivity between all VPCs and the on-premises network via AWS Transit Gateway. Additionally, certain VPCs must be isolated from each other while still reaching on-premises. How should the administrator configure the Transit Gateway to meet these requirements?

A company runs a REST API on Amazon EC2 instances behind an Application Load Balancer. The SysOps administrator needs to monitor the API endpoint from multiple geographic locations and receive an alarm if the p90 latency exceeds 2 seconds for two consecutive checks. The solution must use AWS managed services and not require custom code running on EC2. Which approach should the administrator use?
